Friction models for sliding dry, boundary and mixed lubricated contacts
Friction, lubrication, and wear have a strong influence on the performance and behavior of mechanical systems. This paper deals with different friction models for sliding contacts running under different conditions. The models presented are suited to different situations, depending on the type of contact, running conditions, and the behavior of interest. The models will be discussed from simula...
متن کاملLinear stability of steady sliding in point contacts with velocity dependent and LuGre type friction
In the present work the influence of a LuGre type friction law [cf. to C. Canudas de Wit, H. Olsson, K.J. Aström, P. Lischinsky, A new model for control of systems with friction, IEEE Transactions on Automatic Control 40 (1995) 419] on the fundamental mechanisms resulting in linear instability of steady sliding in point contacts is investigated. Both a velocity-dependent kinetic friction coeffi...
متن کاملA Numerical Method for Friction Problems with Multiple Contacts
Friction problems involving "dry" or "static" friction can be difficult to solve numerically due to the existence of discontinuities in the differential equations appearing in the righthand side. Conventional methods only give first-order accuracy at best; some methods based on stiff solvers can obtain high order accuracy. The previous method of the author [16] is extended to deal with friction...
متن کاملInfluence of electric potentials on friction of sliding contacts lubricated by an ionic liquid.
Tribological investigations on the macroscopic scale revealed that friction can be influenced in situ by applying electric potentials, if electrically conductive fluid such as an ionic liquid is used as a lubricant. Enrichment of charged ions at a steel interface occurs by applying electric surface potentials in a three-electrode setup. As a consequence, the lubrication conditions change. It is...
متن کاملSliding Objects with Random Friction
We study the motion of elastic networks driven over a random substrate. Our model which includes local friction forces leads to complex dynamical behavior. We find a transition to a sliding state which belongs to a new universality class. The phase diagram comprises of a pinned state, a stick-slip motion phase, and a free motion phase.
